A transfer structure for a vehicle which retains a stable amount of lubricant in a coupling chamber and maintains a cooling effect for a coupling by agitation of the lubricant irrespective of an inclination of a vehicle in a front-rear direction is provided. The transfer structure includes a gear chamber (Z1) housing first and second gears (13, 14) meshing with each other; a coupling chamber (Z2)housing a coupling (20) provided coaxially with the first gear (13); an introduction path (90) which introduces a lubricant in the gear chamber (Z1) into the coupling chamber (Z2); and a return path (94, 95, 96, 91) through which the lubricant in the coupling chamber (Z2) is returned to the gear chamber (Z1). The return path is inclined downward toward the gear chamber (Z1) from an opening (94) that opens in a lower part of an intermediate part of the coupling chamber (Z2) in a vehicle front-rear direction to an oil discharge hole (95) that opens in the gear chamber (Z1). 本发明车辆的分动结构即使在润滑油低油位化而降低了搅拌阻力的状況下，也能与车辆的前后方向的倾斜
